Not to enter into technicalities, which to be

a removable cap, the telephone re-

center of this cap, or outer service of the tel

or houses in the same street-that is to saw
over short distances-it is not even necessary
for the speaker to stand close to the instru-
ment or TO raise his voice above its ordinary
diapason. OF course, when the distances are
great as was the case in the recent expert
ments, the operator must approach the APP

mouth to it nor shout as with all other sys-

This alone it must be admitted, is an i'm
mense advantage, on the score of comfort
and convenience, but there is another which
have alluded to and that is its cheapness
the whole apparatus can be made and set up
for fifty cents, and it can be applied to the
wires of any of the electric bell apparatus IN
existence, whence il follows that its general
adoption, which appears to be certain, must
introduce complete modification of the
present forms of telephone intercourse. At
street doors, in the inner rooms of private
houses and hotels everywhere, in short
where telephony is employed, DIR. Herz's
micro-telephone push-button is applicable,
and makes it possible to give and receive
orders, to know who rings at your door and
what his business is, without moving from
your chair, and to know also that there is no
mistake about the individuality of your in
terlocutor, as the tone of the speakers voice
is perfectly preserved. Its advantages in
everyday domestic life need not be dwelt
upon, as they are self-apparent; and no one
can pretend to deny that as a means of com
munication between railway wagons and
conductors of trains the invention will be
highly appreciated by the public, which is
prepared to be becomingly grateful for any in
